Product Overview
The SilverStone FP57 is a smartly designed device that converts a 5.25” drive bay into a 3.5” hot-swap bay. It has very short depth for a hot-swap bay to allow it to fit inside many cases and is designed to also be stackable. When two FP57 are installed together, their combined mounting holes in the rear can be used to mount an 80mm fan, while three FP57 is capable of support up to a 120mm fan for great cooling. Other notable features that makes this device a great buy include independent hard drive status LED, tool-less hard drive installation, and removable front dust filter.Features

Rated 3 out of 5 by Chief Bit on the cheaply made side, but functional
I would not recommend this for someone who is constantly switching drives, it is not the best quality, but for occasional use (weekly backup in my case) it gives an easy access full sata connection from outside the case at a very low price point.
So recommended for those who now why te=hey are buying it!

Rated 2 out of 5 by Jelahd badly designed, too flimsy where it counts, awkward to use
There are much better ones around.
The slider to open the drive bay cover is just plain stupid.
